Greetings!
Writing can be a challenge even when it's not in a foreign language! Your desire to learn, though, will help you get through. One thing that helps to improve writing, whether in one's own language or a new one, is to read, read, read! It might not seem like it, but reading can make a huge difference; you pick up on things, both consciously and subconsciously, when you read that will help you when it's time to write. When you know you have a specific problem, like writing too-long sentences, that's half the battle--you know what to be on the lookout for! Whenever you write a sentence that you think might be too long or complicated, ask yourself: how can I simplify this? What is the simplest way to say the same thing?
Also, when you have an essay you need to turn in, feel free to post it here so we can give you editing advice! You can learn from your mistakes, and improve your grade at the same time!
Best of luck in your studies, and I look forward to reading your work!
